This invention relates' to machines for making link mesh fabric, 'such'as 1s commonly used in the manufacture of ladies f handbags and othersimilar articles. More specifically, the invention is directed totheVprovision of a machine for the production of link mesh .of an ornamentalcharacter con-y taining links-l of different colored,materials-Aaccording to selected` arranged in the fabric designs or patterns. l

Machines ofvarious types are in use at the present time for making linkmesh, and these machines produce the mesh in the. formof a cylindricalsleeveor in the formA of a-flat` Web or strip. The links of'vvhich thefabric is composed are. usually made of Wire of a preciousorasemi-precious metal, and in some of these machines the Wire is ledfrom a supply, usually in the.. form -ofy a reel, to link forming tools'iny whichV suitable lengths: of Wire are severed and formed into 1ringswhich intermesh'with those of: they piece of mesh. In these machines themesh rand the link forming tools relative movcunent, andthe tools.operate to insert a vlink at each period of `rest of'this movement.Son'ietimes several sets-0f tools.r

are used in a lmachine and these tools insert links in successive rowsin the piece, but cach' operationof each set `of tools forms butV asingle link. In such machines aV single kind offwire is employed and thefabric produced has a plain undecorated appearance.

Y The machine of the present Iinvention is designed to produceornament-al mesh and is arranged andl constructed .so that a pluralityof `supplies of or ot' Wires differing in surface appearance may beused, andl sothat links kmade of these different kinds of Wire Vmay bevincorporated in the fabric as the mesh making operation progresses. Anautomatic controllmechamsm is employed which causesfwire tor/.bev

fed from the different Ysupplies tothe link forming' tools in aypredeterminedl order of-V succession, and variouspatterns may thus `beformed in the fabric colors.. y ,y ,f l :w

The principles of the invention may be utilized in connection with meshmakingmachines of any oftheV various Vtypes now fre-y quently usedforthe purpose. Among these machines are those in Which-the mesh is madein the form of a sleeve, others'ivhich make flat-strip mesh, machines inwhich the are given a step. by stepr different kinds of wire is providedof. which is by links f of 'contrasting` best for the' purpose ofproducing the orna.A

mentalmesh is that' in Which the'mesh is made in the form of a sleeveand has an up- Ward movementas successive links are added. at the loweredge of the piece.` `'lliisimanhine is provided ivith'lafpluralityofsupplies of different kinds of Wire or Wires presenting'y differentsurface appearances, and automatic mechanism. forregulating' theoperation of the machine so, that links are made from theseWiressuccession, so that the make. links of. any of determined .point inmachine will begin to the W1res at any pre- 4its operation,- and soVAthat the shiftffrom onewire to another may takeplacea'fter anypredetermined number of links has been completed. This automaticVmechanism includes a-,mastercontrol device.

of such a construction that it may bek used to produce any desiredpattern, and when suitable adjustments have been ymade to-pro'- kin anypredetermined order ofk duce such a pattern, a piece of mesh Will bemade' .in whichlthe patternis continuously repeated.

In mesh making machines of thev sleeve type, the wire is fed from thesupplies to link forming tools which edge of the piece offabric. Intheoperation of the tools a piece ofwire of Athe proper length is severedfromthe supply. This severed length isbentto `form a staple, the. stapleis advanced toward the mesh so that its legs enter a pair of ringslyingside by side kat the edgeof ,the mesh,-and then the legs of the'staple are bent-so as toV form a closed ring., Each ofthe supplies ofWire withy yits individual feedingl device, and thecontrolmechanism,`the action governed in accordance with a pattern vcauses oneof thesefeeding devices to Vcome-into action Whenever a link is to beformed by the t0ols,-While}the other-feeding devices are lh eld'inactivi v The Vautomatic mechanism Whichfcontrols the action yof .the Wirefeeding devices 'is driven by the 'power driven mechanism of theVvmachine and is timed'fso as to operate in correspondence with the stepby stepy movement of the piece of mesh relative to the Y make the ringsand Y cause them .to intermesh Withhrings at the ferent supplies ofWire.

f. directed properly with one supply oit'. Wire. It thenbrings 'toolsand the operation of these tools in the periods ment. operation governsthe control ol' a device Which serves to direct the Wire being 'fed tothe tools. This guiding device includes a block which has passagesthrough it corresponding in number to the vnumber ot dit- The Wirecoming troni the suppliesl to the tools is led through these passagesand when a particular kind.

of wire is to be fed the block Will beV positioned by suitable devicesunderthe control oft the master mechanism so that the passage in whichthat wire lies Will be in regis' try with the tools.. Consequently,Whenithe feeding devices associated with the supply of that Wirea're'actuated the Wire Will loe` so that the portion which is passedthrough the blockvvill be in such position that it may be acted on bythe tools. The master controller governs rboth the operation ot the'feeding devices associated with the several supplies of ivire and alsothe position 01; the block above referred to, and at selected intervalsthe control mechanism tunctions to discontinue the operation ol thefeeding device associated into action the feeding device associated Withanother supply ot Wire, from which links are next to be made, and at thesame time causes the block to be moved so as thereafter*opposite thefeeding point of the tools.

lit)

This master control mechanism includes a pattern control device which.determines the order ot succession of the feed 'from the differentsupplies ot Wire, the times during the operation oit' themachine whenthe shift Will be made from one supply to another, and the number otlinks which will be made from each supply before the shift is made toanother supply. This pattern mechanism may have various forms, but oneconvenient .torni includes any element having a succession. ot patterncontrol areas mounted thereon. An endless chain may be used for thepurpose, having pattern control blocks mounted on it at the desiredintervals. This chain is carried by a support so actuated that the colorcontrol areas on the chain are brought successively into effectiveposition to exercise their control over the wire feed-- ing devices. Thecolor control blocks on the chain areof different shapes, and there areblocks ot as many different shapes as there are diterent kindsot Wire tobe used in the mesh. Controlled by the blocks Vis a member which iscaused 'to assume differentfpositions of rest, which are determined bythe shape of the block which is in elective position. As the blocks arebrought movable y il to placel the passage for the wire which is tobefed successively into effective position, the meniber assumes apositionfof rest Which is de` termined by the block then in place, randalso actuates suitable .means whereby one ot the. .feedinngldevices will.be Vmade active While all the others are held inactive. VAccordinglythe shape of the block which is brought into effective'position willdeterlinine Vfrom which supply of Wire a link is to be made, and byproperly arranging the blocks .on the chain, mesh offany desired patternmay be produced. Insteadot' using a chain I contemplate the use of arotary support `having members of different shapes arranged initsperiphery according to a selected pattern. These members ymay take the:form ot lilocksor pins,-havingdiiierent heights, .and these blocksWould servevtne same `purpose as the blocks carried by the chain; thatis, would determine the position of rest of lthemember .which controlsthe action ofthe .wire 'feeding .devices The use ot' the chain, however,is a convenient Way of producing mesh in Which the pattern is quitealong.-v For this reason the chain offers -soine advantages over othersimilar devices which could-be used for the nirpose. Y l

Forthe `production ot a mesh ot intricate pattern it inaywbe necessaryto control the formation o'lieacli separate link in theliab-y ric.yAccordinglythe control chain Will have as many blocks as plete figure otthe pattern', andthe blocks will bebrought successively into operatingposition, one block per link. However--, it is frequentlydesirable toproduce ,mesh in Whichstripesfor bands of a solid color occur. Suchmeshcan of course beproduced by the use. of a i chain in v the mannerdescribed, but `Whenever a band is being Yformed along series ofidentical blocks appears in the chain. These'blocksarebrought,successively into action, but no change in the action oi thefeeding Idevices occurs because the same Wire y:is to Ebe usedthroughout the series. lUnder theseconditions, the pattern i Withoutmechanism is actuated :tor each-link useful result and 'consequentlytheparts oi`: the mechanism Wou'ldbecome Worn Vto no purpose., In order toavoid the repeated actuation ofthe pattern mechanism, when a longserieso't links are to be made from the same supply of Wire, 'I provideay throw-cti devieewhichV causes parts of the mechanism to remainstationary throughout such a succession oflinks. rDuring this period olinoperativeness the Wire feeding device assoV- ciated 4with the supplyfrom which the series ot links isito be made, 'is continuously kept inoperation. When the.` series of links has been completed the mechanismis again brought into' action, and thereafter the single links of Vthemesh are controlled by the individual block on the chain.

there are l-inksin a com-YY so' v lOl) 'and parts of others.

yOrdinarilyT whenever a longseries of links of the same color lis to beproduced, this sef ries Will take the form of a row or a1plu' rality ofrowsof links extending completelyv Y around or across the piece ofinesh.`Accordingly, the machine-lisV usually arranged so that the throw-offVdevice may be lbrought color can be forined'as singlerows,'=as parts ofarow, or as a succession of complete rows trol of the individual linksis not desired, and since' this throw-ofi" is brought automati-lcallyvinto operation, in accordance with the?.

pattern, the intervention not required. v

'of the operator is `With the pattern mechanism vof the typedescribed,'it will be seen that mesh vhaving 'extremely intricatepatterns maybe pro-" duced and the ligures lwhich constitute apattern.may be repeated as ynfiany' times as may be desired, with each lengthof` mesh which contains a complete pattern'a duplif cate in all respectsof all the otherpie'ces. The length of the pattern, however, isvpractically unlimitedvand, as will vpresently be seen, the change fromone pattern to another is a simple matter which -doesnot require thatthe machine be idle *for any considerable length of time. The machineprovides the maximum degree of control over thelforma tion of the links,and in addition includes mechanism by which theA control maybe -eX-`ercised over the formation 'of groupsr fof links as well as over singlelinks.- In the accompanying drawings,

"In these drawings, the machine is seen to j consistfof a main bed 35,whichfis'mounted on legs 36in any convenient location. As illustratedVin Fig. 4, the macliineis mounted'on as table 37, having legs' 38resting on the floor. VMounted centrally lof the bed 35 is a: block 39on either side ofwhichare carried link forming tools.` Two vsets oftools are vshown in use in this machine, and these tools operatesiniultaneously -to produce links m successive rows. As will presentlyloev described,` the mesh is in the form Vof a sleeve,:which is `given astepby step movef ment relative to the tools.. In theV course `of thismovement the lmeshfisLn'ioVed up-H wardly `so. that the movement may beVdescribed asbeing spiral withrespect to the rows, so that upon each'complete rotation of the sleeve of mesh, two'rows of links will .f

tools.A` .The tools form y*links of successiveV mesh are, in general,lsimilar to those shown inthe Pratt Patent, kllo.,948,615, datedFebruary '8, 1910, it is not necessary to describe these parts in anyconsiderabledetail.

Secured in the top ofthe block 39 is a ring 40, having a double spiralgroove formed in its face. On-top of the block 39 is an upper block41,*bolted `in place, and a ring 42 runs freely ina channel formed inthe face of the upper block resting on ball bearings which run ontop ofthe ring 40. The ring 42 is formed with alternate vertical ridges anddepressions in its outer face. VEncircling the parts described is asleeve 43, which is freely rotatable on the ball bearings on a support44. This'sleeve has its inner face provided withv alternate verticalridges and depressions and itsupper end has a flange 45 which has teeth..46 f orn'ied'in its edge. The sleeve is driven With a step-Wisemovement of rotation by means of a swinging paivl 46 carried on avertical rod which is actuated by a cam 47 on the main cam shaft. AsWill be understood, the links in a piece of mesh tilt in oppositedirections in alternate rows, and this slanting position of the links istaken advantage of in supporting and moving 'the sleeve. Thedoublespiral groove in the ring 4()v cooperates With the vertical ridgesand depressions inthe sleeve 43 so as to grip the links ofthe mesh quitesecurely and as the sleeve is given a rotational movement, as Willpresently be described, the mesh is caused to move about with the sleeveand to have an upward movement which is imparled to it by the spiral.groove. The piece of mesh which is shownin dotted lines, asindicated at47, extends below the end of the sleeve .43 and along this edge newlinks are added. The sleeveis given a stepv by step movement., such thatthe sleeve is advanced by the diameter of one link at each step, andduring the periods of rest of this step by step movement the linkforming tools operate to insert links at the edge of the fabric. Thelink forming tool lassemblies are shown largely in diagrammatic form, asthese devices are well known in the art.

The operating parts of the tools are driven by a main shaft 48 suitablysupported in brackets beneath the bed of the machine, and this shaftcarries bevelled gears 49, meshing with similar gears 5l) on verticalshafts 5l.

A Theshaft 48carries a pulley at one end with a suitable clutchmechanism 48 and at the other end is provided with ahand Wheel soV thatthe machine may be operated by hand, should it be necessary to insertone or more links at some point Where links are missing from apiece offabric. Each of the vertical shafts drives one of the tool assemblies,but

oneiof which Will-be described since they are duplicates. Mounted on thevertical shaft l51 is a disc 52 carrying an eccentric pin 53 encircledby a roller. Mounted in a sliding` block V54 Which runs inguides carriedby upright 'standards 55 mounted on the-bed of the machine, is a plunger5G, carrying discs 57 Whichlie on either side of a cross piece 58 havinga slot in which the roller 53V is re' ceived. As theshaft 51 rotates theeccentricity of the pinQ causes theplunger to be reciprocated toward andaway from the cen tral block about which the sleeve Vof mesh issupported. This plunger consists of ak cylindrical housing 59 intheforward end of which isfmounted the plunger proper, which is made upofa cylindrical body GOin which is threaded a tubular member G1. Thefree end of this tubular member carries apair of prongs 62. Threaded inthe member 59 is a die rod, the outer end of which is shown at 63, andthe .prongs on the member (il are adapted to be spread apart bythe'end'of the die rodwhenfthe die rod is moved relatively to thetubular member. The latter carries a depending lug G4, held in- Vplaceby a lock nut. Thetubular member 6() is heldin vplace in the cylindricalhousing 59 by spring means so that as the complete vplunger assembly ismoved toward the sleeve of mesh, the depending lug G4 strikes against astop carried on aguide block 6G .in which the tubular member Gl isfreely movable, but the die rod will continlgleto move so'thatthe endcarrying the die Will be forced between the prongs 63. Y

Mounted in va suitable channel vformed in the block (i6 is a pin whichlcarries a .knife 67. This pin carries lever atits outer end which isactuated'v by a swinging lever 68,' shown in dotted lines in Fig. 2. Theend of the lever' G8 is movedby a Vvertically reciproeating lever 69which isactuated by a cam 70 011 the main` cam shaft. over the face-of afeed block 7l, shown more Vclearly in Fig. 2G. The outlet end 72 of thisfeed .block 4lies flush against the side of a channel formed'in theblock ('56 anda leaf .spring 73 mounted on the stationaryblock. bearsagainst `the uppersurface of the 1novable guide block. This guide blockhas three channels 74 formed in .its surface', a portion of the channelsbeing coveredby a plate 7 5. At the rear end the block carries the endsnected to one of the channels in the block at one end and at the otherend to a part of one of the Wire feeding devices. The 'wire is fedthrough these tubes from the :supplies to the. channels being deliveredout -into the Vslot in the block GG by the operationv of the feedingdevices. Also mounted in a channel in'theblock G6 is a pivoted lever 77,the rear end of which bears against the top of a rod 7 S, cariyingl aroller bearing against the surfaceof a cam 79 on the lmain shaft of themachine. The forward end of the rod 77 carriesa mandrel ino The |`knifeslides of tubes 7G, eachof Whichis cone.

of the machine7 wire-is fed -fromfone of the wire feeding devices,through-its channel in.;

the block 71.v lAt vthis time theS'block'-71 has been moved tosuch aposition as to deliver the wire` properly to the tools. This movement isbroughtaboutby thepattern control mechanism,- as will presently,Y bedescribed. A length of the kvwire being` fed yis delivered into the slotin the block 66 in front ofthe knife mechanism carried by the rod 67.The` end vof this wire bears' againstl a springpressed stop 81. Theknife is then rocked'so as to sever the lengthr of wire and the sprlngpressure of the stop holds it in Vplace until it can be picked up lbythe tools. The knife Y now` swingsbackwardly out of the way and themandrel 80comes into position behind the piece of wire. The plunger'assembly of the tools now moves forward, andthe severed length of vwireis formed into a staple by the coaction ofthe mandrel, thefprongs, andthe end of the -die rod. This staple will beheld in a 'suitable'channel'formed inthe face ofthe die rod the'end of` which has a` semi-circularform corresponding to the shape to be given the staple. At 'thelprevious movement ofthe support, carrying with it the piece of mesh, the'piece of mesh isbrought torest in such position.that a pair of linksarein front' ofthe vlegs ofivthe` staplefand as the plunger assemblyvmoves forward, carrying with it the staple, the legs of the latter areinsertedthrough these links.

The staple must now be closed and this is effected by means of a die rod82mounted in a channel inthe block 39. l."This/die rod has a face whichcooperates ywithfthe faceofthe outer die rod and when the two are'yforced' together the staple will be formed intoa complete ring by theircooperation;v :Thein-k ner vdie rod`82 extends vthroi'rgh the blockwithy its rear end enteringachannelrfin. which moves a verticallyreciprocating rodV 83 which is raised and lowered lbyf means of a cam.SL1- on the main shaft. At its upper end this rod has inclined surfacesV85 and as the rod is raisedthe'inner die rodisfforced outwardly intocooperation with the outer die rod. A spring :86. holds *the* rod 83against the face ofthe cam, and the ldie rod is also provided with aspring which serves to keep its rear face in 'Contact with theinclinedsurfaceofthe rod 83.

The parts which have no'w been described' constitute the mainfeaturesof'thetool as- A sembly, and two setsl ofV these toolsare em?ployed in the present machine, Y inserting links at diametric'allyoppositev points on the sleeve.V The operation-i of the tools andthemovement of the mesh support is'properly timed so that during thoseperiods when-the mesh is moving the tools are inoperative andy as soonas the sleeve of mesh Lhasy cometo rest the several parts of thetoolfassemblies each revolution larey broughtinto action in the pro iertimed relation. vAt each .operation of ytheztools a l.single link isrformed,vbut with'twogs'ets of' tools this? machine produces two linkssimultaneously. The two links'are insertedin successive.rows,fhowever,so that upon each complete' rotation of the sleeve of ine-shtwo completerows ofy links will have been added tO1lZ'."" ,f l -As shown in Fig. .1,the presentrnachine includes three differentl supplies of'wire 'for eachset 0f=tools1f The reels on whichfthe Y lwire is carried are notillustrated in the drawings, but the wire isled "from these-f reels tothe individual feeding devices, and is thencey fed tol the feed blockwhere vit-is delivered .to the tools.-v The feeding.devicesl are ofsimilar construction and. but one need be described; Such a feedingdevice is more clearly illustratedin Figs. 5,6, and 7, where the feedblock 71 is shown mounted kin the block 66. Leading from the rear endof'y this block is the tube 76 this tube 'leads to central slot 88. Athe standardand shaft 89r extends through carries a* gr'ooved roll 90whichlies in the slotl 882 Above'fthe`roll90 lis a similar roll 91carried'on a shaft 92 previously described, and a standard 187 having awhich is Yheld in bearings 93 movable in a slot 'formedrvin'th'eupright.y Springs 94press against these bearings and thus causethe rollsandv 91 to be held with their faces in. contact.. The depth of eachlgroove is somewhat less than one half the diameter of` one of the wiresto bek fed. Consequently as a' wirevis led'from the supply between therolls the upper rolllbearing against the lower roll Vby the springpressure. willcausc the Wire to be firmly gripped. On ltheshaft 89 atoneside yof the block,y is a spurj gear95, meshing with a similar gear96 on the shaft 92. lOn the other end of the lshaft 89'is ay ratchetvwheel V97 and swingingly mountedA on .the end of theshaft89 beyondthefratchet kWheel is alever 98'which carries a spring pressed pawl 99.`The lever 98 is connected by a link 100 to a bell-crank 101, pivota'llymountedfin the bracket below the table. The other arm of the bell crankcarries a roller 102, bearing against a cam 103 on ythe main shaft, andthis ycam is designed so that upon of the vrmain' shaft the lever 98will be rocked so that if the pawl 99 were free to do so, 'it vwould`cause theffif'atchet to beadvancedby one step. The diameter of theVwheels' 90 and 91 and the size of the ratchet teeth, are suchhthat onemovement of the ratchet *will v`cause a vlength of wire sufficient for asingle link to be fed by the Mounted in a slot in the upright 87 rolls.

an enlarged portion 106 which passes through jagbore formedinthe table'and at is a rod 104, carrying a pin 105 which lies beneath the pawl99.". This rod terminates in noV 107, the construction and operation ofwhich will presently be described. This `control bar, however, 1sprovided with notches 108,

into whichzthe pointed end of the portion 106 enters, and when the baris in suelrposlposition that the pin 105 lifts the pawl clear differentsupplies in of the ratchet. A feeding devicesimilar to that described isprovided for each supply of wire.A Each of these feeding devices isprovided with actuating means such as the bell crank 101, and the cam103 which causesl the leverv 98 to be swung each time a length of Wireis to be fed. Only one of these feed* ing devices will be renderedoperative at a time and the feedingdevice which is to be effective tofeed wire is determined by the position of the control bar 107. Thelatter is moved to different positions bythe pattern mechanism.

Mounted on the forward end of the machine is a frame 109 which carriesthe mechanism by which the feeding' of wire fromthe a selectedl order ofsuccession is brought about. A front elevation of the mechanism isillustrated in Fig. 4. At the left hand side of the frame there ismounted a wheel 110, having a groove formed in its periphery. Thisgroove-111 as shown in Fig. 18, is formed to receive the links of achain 112, and the chain carries blocks of three different kinds Thefirst of these, 113, has a raised' portion 114 near one end thereof, andanother fiat portion 115 along the side of the raised portion. The endof the raised portion 114 and the flat portion 115 serve to determinethe position of rest of an element which, in turn, controls the wirefeeding devices and the arrangement of these surfaces, as shown in Fig'.13, corresponds to the feeding); of one 'of the different kinds of wire.The block 116 ,has a central raised portion1 the end .of which has agreater area than the end of the'raised portion 114 on the block 1-13.This type of block corresponds to the feeding ofV a different kind ofwire. The third type of. block 117 has a flat portion 118 and araised`portion 119, but these parts have an arrangement opposite to thatin the block 113. Since this machine to feed three different kinds ofwire, three different types of block are employed, as described, but ifa greater number of kinds of wire were to be used inl the manufacture ofthe mesh then blocks of other shapes` would also have to be em' ployed;one for each kind of wire to be used. In Figs. 14 to 16 there areillustrated face views of the block and in Fig. 17 a sectional view. Itwill be seen that the raised portion against slipping so that the4blocks may be n suitably positioned with reference to other parts of themechanism.y I

Mounted on the main shaft 48fof the machine is a spur gear 121' whichdrives a gear 122 mounted on the stud in the bracket. This gear drivesanother gear 123, shown more clearly in Fig. 8; The gear 1231s mountedonl a'l stud 124, also secured in the bracket 109. Keyed to the stud 124is a double surface cam 125', andina cam channel 126, formed'in thiscam, runs a wheel 127' mounted on-a plate l128. This platehas a J pairof longitudinal slots through which are received bolts 129 byl whichVthe plateV is mounted for 'sliding movement with refer ence to the frame109. vided with a spring 130, which holds the cam roller 127 against thefacefof the cam. Mounted on the upper face of the plate Vis aspring-pressed pawl131- which engages vthe teeth of a ratchet wheel 132,which is mounted on the stud supporting the wheel 110.l This ratchetWheel 132's fast on the wheel. As the main shaft of the machine rotates,it drives the gear 123 at the saine rate of speed and consequently thecam rotates once per revolution of the vmain shaft and causes areciprocation of the bar 128 and the advance of the ratchet wheel132once per revolution ofthe main shaft. As the link form# ing tools areoperated at each revolution of the `main shaft, it follows thaty theratchet Wheel is advanced one step per link. i The ratchet wheel is soproportioned that at each stepA two links of the chain are fed forward;The chain, asshown in Fig'. 13, carries a blocken every other link.Consequently a The plate VisY pro new block is'vbrought into positionwhenever Y a linki's formed. Each block controls theA formation of asingle link inthe mesh, and the'shape of the block which is brought intoeffective position by the step-wise rotation of the ratchet Wheel 132will determine from which ofthe ysupplies of. wire a length of wire forone link is tor befed.

Mounted below the table is a curved tube 133j into which the slack ofthe 'chainVdiarannnatically indicated at 134,` is received.

The chain enters this tube, which is of con-V siderably greater diameterthan the chain and the-slack piles up within the tube. `The e chain isendless, and passing out of the lower end of the tube '133 it is ledupward and `through a guide tube 135 which is suitably mounted -on theframe 109vso as to guide a stretch of the chain directly to the wheel110. yVVlth suchv an arrangement, an eX# chain is received inthe tube133 and isthus (ill tremely long chain maybe employed withf outinconvenience, -sincethefslack ofthe kept from injurymand also preventedfrom tangling. The use lof such a' long chain makes it possibletoproduce an intricate patternin Vthe mesh, as will be seenfrom thefurther description of the pattern mechanism.- f v t I Mounted in asuitable bracket'136, extending outwardly from the face of theframe 109,is a slide'137which has dove-tailed edges 138 which enter suitableguide-ways formed in the bracket. *Beneath-'the slide is a. roller 139mounted on a stud, this roller entering a channel 140 formed in thevdouble cam 125. These parts are shown more clearly in Fig. 8, and thechannel 140 is sofformed that the slide 137 is movedtoward Yand awayfrom the face ofthe frame 109 at each krevolution of the stud 124. Thevdouble cam is vkeyed to this stud, as is also the gear 123.

Mountedfin a housing 141 extending up-` wardly'from the slide, is apairy of feelers 1 42 and 143. These feelers are placedone aboveanotherand vhave recesses'. formed in their yopposed faces through-whichextends a pin 144, on which is pivotally mounted a lever 145, which ispivoted, as shown in Fig.` 11, to each of the feelers. The forward endsof the feelers `146 are placed so as to vbear against the color areas-onthe blocks and as shown in Fig. 11, a. blocksimilar to 113 is inregistry with these feelers. The-upper feeler bears against the' end ofthe raised portion 114, while the lower feeler bears against the surface115 of'this block. `As the slide 137 lis moved towardv and away from theface of the frame 109, bythe action of the cam channel 140, the ends ofthe'feelers bear against the inclined surfaces 1207for'med on theblocks, and the position of the feelers relative to the housing 141 isthus determined by the shape of the blocks'. When the slide is beingreciprocated so that thefeelers f are clear of the blocks on the chain,the chain will be advanced by one block. Then the slide is moved back Aand' thefeelers bear against the surface of the block, assumingpositions of rest whichare determinedby the shape of the block. Theposition fofthese feelers alsov determines the position ofthe lever 145,which iscentrally 'pivoted on a iixed pivot and may be swung on thispivot' by the relative movements of the feelers;

Mounted in thev slide 137 Yis a second slide 147, having` lthe shape ofan Vopen center frame. This second slide is vshown `more clearly in Fige. 20 to 22.

In Fig. 20 the slide147is in ajposition corresponding to the positionofthe feelers, as determined by a block 113. fAs'seen in Fig. 11, such ablock causes the lever145 `to take theposition with its lowervend swungto the This correspondsto a` shiftV of the left. small slide 147`upwardlya`s shown in'Fig.y 20. Accordlngly, when the extension .bearslagainst the slides 151, 152, the slide 151 'is moved tothe right, asseen in F ig.'20, while vthe slide 152 is moved to the left. Thelever153 is thus swung with its upper end moved to the right. In-Fig.' 20 theslide A147 klies in the position such asit wouldffreceiveby the contactof vthe feelers with the block 116.

At, its forward endthel bar has downwardly extending lugs 157 between which is received aroller 158 on the upper face el the lever 153. As the lever 153 is swungby the relative movements et the slides 151 and 152, the bar 107 will begiven different longitudinal positions et adjustment. It will be seenthat the mechanism is such that the shape o'l' the blocks on the colorcha-in will determine the position ot adjustment given this bar. 4ln thepresent machine two sets et link forming tools are employed, and asingle control mechanism controls the wire teed to each oi these sets ottools. rthis construction is not essential, since it is possible toprovide separate patev tern meclianism `for each set ot tools so thatthe feeding oit the wire to ditlerent tools would be individuallycont-rolled. In the present instance, however, both sets ot tools aresimultaneously 'l'ed with the saine kind ot wire, but trom'di'ilcrentsupplies. Accordingly, the single pattern mechanism controls the 't'eedtrom two di'l'i'erent groups ot wire supplies, and two control bars 107are provided, connected together by a rod 159. The control bars havenotches 108 Jformed in their upper surfaces and the enlarged extensions106 of the rods 104 bear against the upper suriace oi the control bar.The har 107 is capable ot beingl placed in three dili'er entv positionsof adjustment, according` to which of the three (liti-cient blocks arein position. In each such position ot adjustment one ot the notches liesbeneath the portion 106 of one oi the rods 104. `When that roll dropsdown its pin 105 clears a pawl on one of the wire 'feeding` devices andaccordingly that wire :t'eed is brought into action. rlhus the differentpositions of adjustment ot the liar, as determined by the blocks on thechain, result in one of the wire 'feeding devices being'y renderedeffective, while thc others are maintained out of action., and thearrangeA ment of' the notches 108 in the bar is such that but one feedmechanism is eii'fective at a time.A Mounted underneath each branch etthe control bar is a small cam plate 160, having; areas as shown in Fig.29, oil three diiterent heigilits. A lever 161, pivotally mounted'beneath the bed ot the machine, has a roller at one end which hearsagainst these surfaces. At its other end the lever supports a rod 162,which extends upwardly through a bore formed in the frame, and throughthe block` 66. The movable wire block 71 has a downwardly extending' rod163 which enters a bore in the block 66 and rests against the upper endo'l the rod 162. The arrangement is such that as the control bar isshi'lfted longitudinally to the different positions of adjustment, thecam plate will cause the lever 161 to be swung on its pivot, the extentof the swing being determined by the height of the surface against whichthe roller bears.

land the parts are' designedl notch 108 1s lunder oneoit' the rods'1041: sons In such swinging movement the wire; block 71 will be gireudifferent positions ot rest,

to cause wire to'be 'ted from the supply at the sametime the wire blockTi will be positionedby Athe cam plate v160 so that wire troni thatsupply will be properly delivered tothe link toi-ming tools. Thepositions oi' rest oit the bar 107 thus i'leterinine not only which etthe wire teeds will. be eiiective, 'but also cause the wire guide. blockto be properly positioned so as to deliver thiswire tothe tools.Accordingly,the shape of the blocks on the color chain exercise controlbeth over so that when a theiteeding of wire and the guiding oi' thewire being' fed to the tools. I

lith the mechanism soA described, the color chain is'advanced onestep,gor one block, each time a linkis 'iorn'ied` Each block on thechain thus determines the kind oi wire which is to'be used in ctcrringto Fig. :28, in which there is shown diagrammatically, a piece otpattern mesh, the light links, designated by A. may be made of anyo'tthe three kindsvot wire arF ranged according to a selected pattern.I-lowever,` the pattern which is to he produced'in the meshmay'requirethe forma tion of a singlerow ot links have the same color. Such a rowof links across the piece of mesh could be produced hy the use of achainin which there was a succession oi' blocksV all ot' the same kind,corresponding to the kind ot wire to be used in this'row, but during themanufacture otl this row' the pattern mechanism would be actuated eachtime a link is 'termed but since the blocks were all alike no change inthe position ot thecontrol. bar would follow. rlhe actuation ot thepattern mechanism, therefore, would not'produce any useiul result, anditis desirable to avoid needless wear on the pattern mechanismwhichwould result from such a situation. It also may be desirable to producea mesh in. which there appears a strip or band, indicated as C-D, madeupoi` a plurality of links of the saine color. This is simply anexaggerated case ot the same kind as that previously described, and ifthe `color chain were to control the formation ot each link a longsuecession of blocks, all of the same kind, would appear on the chainand the pattern mechani sm would be actuated each time, but withoutchange in the position lit is desirable to arrange as to permit a singlerow,.a part of a row, or a series ot rows, to be made up ot links of thesame kind ot wire without the necessity ot bringing the patternmechanism into action tor each link of this series, Thepresent patternmechanism is arranged so as to permit the mechanism to be held at restat' selected intervals, correspondingz,` to the 'tor-1V single link,

Thus, by suitably forming the controlplate,

Asillustrated, the thf-roiv-oit plate is brought into action by a singlenotch inthe selector disc and the parts rare timed so that the throw-offmechanism will become ettectiveonce per roW.

it desired, lit may have asuccession ot' bands 'ol solid color so thateach block of the cha-in,

instead et corresponding to the 'formation voft Aa single link, willlcorrespond vto the tori'nation ot a -i'oiv o-t' links. The throw-ottmechanism,therefore, pern'iits the action ot tlie7color chain to bemodilied so that a single lilockgoverns the feeding orf Wire for one apart el a row, a tull row, or a succes- V'sion-'oit tull rows. In themachine described the single pattern mechanism controls the feeding ot4Wire tto tivo sets ot tools.

ivould have tour notches instead of three,

`sii-lt 'in the Wire being viouslv seme and that the cam kplate on the"color 'bar would have tour cli-{terent cam surfaces instead ot three.Various other minorfchang'es would also be required in the mechanism. Itwill be seen that the present mesh machine oli'ers numerous advantagesover those previously used for the production ot an ornamental mesh,lsince it permits mesh to be madein which each single link is undercontrol andalso permits the vactiony of the colorV chains, thethroi'v-oit plal'eaand selector discs maybe quickly changed, the changein the operation -oji' the machine troinone type ot n-iesli toan'ot'herdoes not result in any considerable delay.

lVhile I have described the use otl a color chainon which color controlareas are provided, it is also possible Ato make use of discshavingradial projections such vas are shown in the co-pendingapplication of Oscar Soderstroni, Ser. No. 672,271, tiled Nov.v 2, 1923.Such a plate, however, would ordinarily be used `for somewhat -lessinvolved patterns than the chain is capable ot' making.

ln the construction illustrated, I have shown the use of three differentsupplies of Wire, each of which is proyided with its individual feedingdevice. are in the form of reels which are conveniently mounted kat oneside 'ot the machine.

In iront ot each reel is a feeding mechanism ot the typede'scribed, andthe Wire is led from Vthe feeding mechanism through suitable tubes tothe movable guide block. ln

the arrangement shown the reels are placed' side by side along one sideot the machineV and the wire led from the feeding devices to the centralblock has to pass through tubes ivliiclrhave a curved shape. lVithsomeftypes ot wire tl-ie'bend'ing ot the wire necessary to cause it tomove through the tubes may regiven a set vwhich might result in thelinks termed of the Wire opening slightly zitter they viveieincorporated in the 1piece ot mesh. 'ln order to avoid any ditliciiltiesAwhich would result trom the z links thus opening, I have devised theWire feeding mechanism illustrated in Figs. 30 and 81. 'In Fig. 31there' are shown a. phirality ot' Afeeding devices, herefthree innumber, which farle placed in .series instead Vot i These feedingdevices lying sidel by side.` correspond in construction to thosepredescri'bed 4andare actuated in the ay by swingim arms 98 actuated bylinks l0@ connected ivith levers 101 similar lili) rlliese supplies V iio Y rolls being to those shown in Fig; 5. yEach of fthe'wire feedingdevices includes pairs of rolls mount-V ed on shafts similar to shafts89 'and 92, the driveny by means ofgears 95 and 96, as before.
